In the production process of stone paper, rolling technology, as an important processing technique, plays a key role in transforming stone paper raw materials into final paper products. Compared with other processes, the rolling process has unique advantages and can effectively improve the physical properties and appearance quality of paper. This article will explore in detail the definition, process, and importance of the rolling technology in the stone paper production line.
1. What is rolling process?
Rolling process is the process of processing materials at a certain temperature and pressure through one or more pairs of parallel rollers. This process is commonly used to manufacture films, paper, and various composite materials. In the production of stone paper, the rolling process heats and compresses the evenly mixed stone powder and polyethylene resin to produce paper with a certain thickness and strength.
The rolling process in stone paper production lines usually consists of the following steps:
Raw material preparation: Firstly, mix limestone powder and polyethylene resin in a certain proportion to ensure the uniformity and stability of the material. The selection of raw materials and pre-processing have a significant impact on the quality of the finished product.
Heating and Extrusion: The mixed raw materials are fed into an extruder and melted by heating to form a uniform pulp.
Cooling and stretching: Squeeze and stretch the pulp through a roller while maintaining a suitable temperature. This process can improve the tensile strength and toughness of paper.
Forming and cutting: After the rolled film is cooled, it enters the forming equipment to ensure uniform thickness, and then cut according to customer requirements to finally form standard stone paper.
The rolling process has multiple advantages in the stone paper production line, including:
Uniformity: The rolling process ensures consistency in paper thickness and reduces the defect rate of the product. This feature not only improves production efficiency, but also reduces the scrap rate.
Physical performance enhancement: Through rolling, the density and strength of the paper are further improved, ensuring better mechanical properties and tear resistance in practical applications.
Surface gloss: Rolling can improve the surface gloss of paper, making the finished product visually and tactilely more outstanding and enhancing its market competitiveness.
